This invention relates to manually-operated fluid applicators of the general type incorporating a fountain roll provided with a handle. Theppera'tor fills the fountain roll with jfi'iii'dsuch as paint and the like and thenusing "the handle rolls the fluid, onto the surface to which" it is desired to apply the fiu'id.- Devices of this character'fare particularly adapted for paintingw'alls and the like. 7

'One of the 'objectsfo'f this inventionis to provide' a device "of the character described which permits the user to control theamount'oifluid rolled 'onto thework from the "fountain roll. An-- other objectis to provide a device of this character which is-"c'onstructed in 3311111316 and 'inexpensive mannerto provide a reliable device permitting the application to the surfaceof the precise amount of fiuid desired. Other objects may be inferred from the following.

A specific example of 'a'device "constructed in accordance 'with'the invention is illustrated by the accompanying drawings and described hereinbelow for the :purpose'of disclosing the prin'ci--- ples and operation of the invention. Once these principles and operation are understood those skilled in-theart may incorporate them in forms other than are "involved by the specific example whichis illustratedand described herein.

"The illustrated device is amanually operated fluid applicator including in combinati'on'a fountainr roll ll'and a'transfer roll [2. Thetransier roll 12 is longer than the fountain roll I I.

This'prop ortionin'g is efiectedby making the bend I5, of the wire loop with an adequately short radius.

paint or other liquid.

The cantilever beam I6 of the secondly men'- tioned loop has an end 38 curving towards the cantilever arms 13 and I8. The tip of this end 38 has a hole through which one end of a wire loop arrangement is passed. This wire 100p arrangement is made of stiif wire bent to provide a pivot shaft 39 passing through the hole'in the tip of the end 38. From thispivot shaft the wire loop arrangement extends to provide a straight I shifting strut 40 which bears against the cantilever arm I4 by way of a right angular portion 4|. The wire loop arrangement then extends from this portion H downwardly at an angle to form a trigger 42 angularly arrangedrespecting the various arms of the device at a position accessible to the fingers of the operators hand when spanning the respective armsas shown by Fig. l. In operation paint or other fluid is first loaded in the fountain roll in the mannerpreviously described. This fountain roll is then positioned between the oppositely extending ends 23 and. 24 of the rectangular loop portions 21 and 22. Then the operator grasps the respective cantilever arms as shown by Fig. 1. The transfer roll I2 is positioned against the surface to which the fluid is to be applied and the device is rolled along it while the operator squeezes the respective cantilever arms together. The bends Id and I? of the two elongated loops of heavy gauge Wire function together as a spring arm I l biased away from the arms is and .Iil. In the event this spring action is insuflicient or deterioriates with age, the operator uses his fin: gers to pull up on the trigger 42 which then pulls the shifting strut 40 between the end 38 of the cantilever beam I 6 and the cantilever arm I 4 and thus wedges the latter arm downwardly with consequent separation of the transfer roll from the fountain roll. I

.With the device controlled in the above manner the paint or other fluid permeates the covering 36 of the fountain roll 1 l and is absorbed thereby. In turn the covering 31 of the transfer roll I2 absorbs more or'less'of the paint or other'fluid from the covering 36 and the amount absorbed is transferred to the surface to be painted or otherwise treated with the fluid. The covering 36 is always saturated but the saturation of the covering 31 0f the transfer roll is completely under the control of the operator. The operator merely squeezes the handle provided by the cantilever arms of the elongated loops more tightly together or lets up on the force while pullingon the trigger 42 if necessary, all as required to respectively get a heavier or a lighter transfer of the fluid from the fountain roll to the surface to which the fluid is being applied. j

Although the wire loop arrangement forming the shifting strut and trigger is made from lighter gauge wire than are the elongated loops providing the arm I4 and the beam I6, these heavier parts are flexed elastically apart by the shifting strut 40 because so much of the stress in the latter is carried in compression and because the force is applied to the parts It and IS in the form of beam flexure stress.

which normally keeps the ing in combination a fountain As shown by dotted lines in Fig. 2 the user may flex the cantilever arm I4 laterally respecting the other cantilever arms I3 and I8. This is done by manipulation of the arm I 4 with the fingers of the hand grasping the device. This lateral flexing longitudinally projects the free end of the transfer r011 I2 flush with or beyond the arm 22 and permits the use of the transfer roll clear up to and in the corners of right angular surfaces.

Thus the device can apply fluid such as paint on the walls of'a room clear up to and in the corners formed by adjacent right angular walls. The two arm portions 2i and 22 therefore may be used to support the naturally heavy fountain roll I I without interfering with the use of the device in cor- -ners or other close places.
